It is a bit disappointing that T-Mobile isn’t pushing Android 4.1.2, which while a minor upgrade over 4.1.1 is still a pretty useful one. But hey, let us not be negative here and just celebrate the fact that the update is finally available and that the wait is at an end.

So go ahead and check if the update is available from the Settings » About phone » Software updates menu, and get your Jelly Bean treat.
